前序：安裝jdk
- 在官網(wǎng)下載jdk
jdk-8u241-linux-i586.tar
2.通過SecureFX上傳到/usr/local/jdk，并解壓出來
3.配置JavaHome
vim /etc/profile
- 測試java安裝是否成功
java -version
報錯:-bash: /usr/local/jdk1.8.0_144/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: 沒有那個文件或目錄
5.解決辦法：
yum install glibc.i686
由此引出了主題:
This system is not registered to Red Hat Subscription Management
正文：通過yum安裝軟件時，報錯This system is not registered to Red Hat Subscription Management。
- 以下是解決辦法
1.查看系統(tǒng)原來預(yù)裝的yum
rpm -qa|grep yum
卸載預(yù)裝的yum
rpm -qa|grep yum|xargs rpm -e --nodeps
再次查看安裝的yum情況
rpm -qa|grep yum
- 去國內(nèi)鏡像下載以下的rpm安裝包
2.查找的包有
[yum-metadata-parser-1.1.4-10.el7.x86_64.rpm](wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm)
[yum-3.4.3-163.el7.centos.noarch.rpm](wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-163.el7.centos.noarch.rpm)
[yum-plugin-fastestmirror-1.1.31-52.el7.noarch.rpm](wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-52.el7.noarch.rpm)
[python-urlgrabber-3.10-9.el7.noarch.rpm](wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-9.el7.noarch.rpm)
[python-iniparse-0.4-9.el7.noarch.rpm](wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm)
下載完后
3.通過命令安裝
rpm -ivh --nodeps -replasefiles xxx
4.安裝完后，查詢yum安裝情況
rpm -qa|grep yum
5 配置CentOS鏡像
//備份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
//下載鏡像配置文件
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
或
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
//生成緩存
yum makecache
報錯：
6、編輯CenOS鏡像配置文件
vim /etc/yum.repos.d/CentOS-Base.repo
把出現(xiàn)$releaserver的這個變量改成7
- 重新 yum makecache
后序：回到檢查jdk版本java -version出現(xiàn)的問題：
報錯:-bash: /usr/local/jdk1.8.0_144/bin/java: /lib/ld-linux.so.2: bad ELF interpreter: 沒有那個文件或目錄
1.重新運行yum install glibc.i686，安裝成功
- 檢查
java -version
